Assuming from your post that the series are all in one big data frame like this:

DF <- structure(list(V1 = c(1990L, 1990L, 1990L, 1991L, 1991L, 1991L,
1994L, 1994L, 1994L), V2 = c(17.24, 18.19, 19.22, 20.11, 20.26,
22.2, 20.05, 24.64, 26.34)), .Names = c("V1", "V2"), class =
"data.frame", row.names = c(NA, -9L))
DF

ser <- do.call(cbind, tapply(DF$V2, DF$V1, ts))
ts.plot(ser, col = 1:nrow(ser), type = "o")
